JAMES R. LOGAN, OF FARGO, DAKOTA TERRITORY.

FEED-RACK.

SPECIFICATION forming part of Letters Patent No, 366,412, dated July 12, 1887.

(No model.)

To all whom it may concern.-

Be it known that I, Janns R. LOGAN, of Fargo, in the county of Cass and Territory of Dakota, have invented a new and Improved FeedRaek, of which the following is a full, clear, and exact description.

My invention relates to an improvement in feed-racks for mangers, and has for its object to provide a means whereby an animal may freely feed, but wherein waste will be prevented.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is an elevation of the doors of a rack viewed from the outside. Fig. 2 is an elevation of the same viewed from the inside, and Fig. 3 is a horizontal section thereof.

In carrying out the invention, A represents the frame of the feed-rack of a manger, and a an opening in said frame adapted to be partiall y closed by doors B B.

The rear edge of each door, whereby it is hinged to the frame A, is perpendicular and the top and bottom edges horizontal. The

doors are narrower at the top than at the bottom, being made to approach each other near enough at the latter point to substantially close the opening a. At the top, however, a space, D, is made to intervene the opposing inner edges of the doors, of sufficient width and length to admit of the withdrawal of a horses head having very little fodder in his mouth. To that end the inner bar, (I, of each door is made perpendicular to within a point near the center, where they are projected at an angle toward each other, reducing the space and forming a contour adapted to the animals neck, as at d, from whence the bars d are further projected inward at a gradual inclination to a union with the bottom bar.

The doors are hinged upon the inside to open inward, as shown in Fig. 2, and the said doors are kept automatically and normally closed against upwardly-extending lugs E, integral with the lower horizontal portion of the frame, one or more lugs being provided for each door, as shown. Thedoors are automatically closed bymeans of a spring, E, which spring may coil upon a rod, 0, passing through the butts of the hinges and forming the pivotal pin, or in any other approved manner. It will thus be observed that the animal may insert his head at the space D and reach far back within the rack, by pressing against the door; and it will be also observed that while the animal may feed with ease and withdraw the head with some fodder in the mouth, any attempt at waste is prevented by the reduced width of the space D and the fact that the doors will not open out to increase the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A feed-rack for mangers, provided with a frame, A, having lugs E, integral with the outerlower horizontal edge, spring-actuating doors B B, hinged to said frame, a space, D, intervening said doors at the top, and the said doors adapted to open inward only, substantially as shown and described, for the purposes herein set forth.
